General Description: * The wear plate is manufactured by depositing high chromium, wear resistant materials on the mild steel base plate using open arc or submerged arc welding process. * Consistent wear resistance guaranteed from surface down to 75% depth of the overlay. * The volume fraction of primary carbides is maintained between 30 to 50% to provide a good combination of wear resistance and homogenous bonding. * Plate hardness ranges from HRC58-65. The hardness is tested on machined flat surface just below overlay surface. * Fine cracks perpendicular to the welding bead is normal due to natural stress relieving in a very hard matrix. * Staggered cracking pattern on overlay surface contributes to good formability. * The wear plate is suitable for severe wear and moderate impact applications. | | |
Typical Applications: Acme plate is widely used in the mining, power plant, port, cement, steel plant, glass, waste handling, glass, dredging, pulp and paper industries. Some applications are as below: * Mining: Hopper and bin liners, Chute and feeder liners, dump truck body liners, dozer blades, shovel buckets, dragline buckets, excavators. * Cement: Separator guide blades, vertical mixer liners, conveying pipelines, screw conveyors, distributors, sintering ore conveying chute, hopper liners * Power: Pipelines, coal feeder chutes, coal hoppers,coal mill shell liner, classifier cones, journal liners, deflectors. * Steel: Bin liners, hopper liners, coke vibrating screen plates, housing liners, sintering fan blade, discharging ducts. | | |
